1) If the ACL between the 2 interfaces is "permit all", does it allow the broadcasts (like netbios) to be relayed to the other interface?
2) And does 515E have an ip address helper? I don't see any commands relating to ip address helper when I do "?".
The version of the pix is:
Cisco PIX Firewall Version 6.1(4)
1) Pix firewalls running 6.x code will not forward broadcasts across it's interfaces.
2) Pix firewalls do have a DHCP relay function which is essentially the same as ip-helper but this was introduced in version 6.3 so it won't be available in 6.1(4) -
